New two-stage he­li­cal bevel gear­boxes with out­put torques up to 50 Nm

NORD Drivesys­tems has added to its lat­est se­ries of slim two-stage he­li­cal bevel gear­boxes with a new smaller unit for out­put torques up to 50 Nm. Highly ef­fi­cient he­li­cal bevel type units there­fore now com­ple­ment the line-up of worm gear­boxes that is al­ready avail­able for small loads. Thanks to su­pe­rior man­u­fac­tur­ing qual­ity stan­dards, the gear units are highly re­silient and with­stand large forces on the out­put shaft. The short-term over­load tol­er­ance is 275 per­cent, which leaves enough time for the mo­tor pro­tec­tion to kick in. Me­chan­i­cal block­ages usu­ally do not cause dam­age, but the drive can start right up again with­out ser­vice in­ter­rup­tion. The new units are avail­able for gear ra­tios from 3.58 to 61.88. They add a new size to the ex­ist­ing se­ries that now com­prises six sizes with out­put torques up to 660 Nm. NORD sup­plies the two-stage he­li­cal bevel gear­boxes with hol­low and solid shafts, sin­gle or dou­ble shafts, for foot or f lange mount­ing, and in open or en­closed de­signs. All ver­sions fea­ture a very high power den­sity, en­sur­ing ro­bust re­li­a­bil­ity and easy han­dling. By de­fault, the gear­boxes sup­port re­verse op­er­a­tion. NORD cus­tom-con­fig­ures mo­tors, drive elec­tron­ics, ac­ces­sories, gas­kets, and lu­bri­cants for all in­dus­tries. One of the op­tions, for in­stance, is the heavy-duty cor­ro­sion-pro­tec­tion treat­ment nsd tupH for the en­clo­sure.­quiry #160223
